General answer on this question is - most of effects and images are function of time. If you want to change the "speed", then you may change speed setting of effect, OR, control TIME. Things like pause, faster, slower - define by time (depends from time), and the place for time - player. Player responsible for time management. BEYOND offer various masters (see Master tab) and for effect control - Time Control tab. So, pay attention to Master tab, and Time Control tab. This is second place to look at (in addition to effect settings).
